Description

Infrared ray bulb and manufacture method thereof and the heating service device that uses it

Technical field

The present invention relates to be used in the infrared ray bulb in the equipment of heating and heating etc., relate to the heating or the heating installation that have adopted the infrared ray bulb and the manufacture method thereof of the sintered body that comprises carbon material and adopted it as the long hair hot body especially.

Background technology

The heating of employing infrared ray bulb of the present invention or heating installation are meant that heating system (for example, radiator, heating installation, air-conditioning, infrared therapy equipment etc.), drying equipment (for example, cloth drying, the bed clothes drying, food drying, garbage disposer, the hot type smelly device etc. that disappears), cooking device (baking box, microwave oven, the baking box bread producing machine, bread baker, roast machine, warmer, roast chicken equipment, baking box, freezing thawing used etc.), beauty appliance (for example, hair-dryer, hair-waving is with heater etc.), fixing (for example, LBP such as the equipment of literal and image etc. on thin layer, PPC, fax wait the equipment that colorant is shown as medium and utilize heat from film originally to the equipment that is carried out heat transfer write by the transcription body etc.) device that utilizes thermal source to heat heating object or warm oneself that waits.

Heater as in the past infrared ray bulb mainly adopts tungsten filament and nickel filament.Because oxidation can take place in tungsten filament in air, so make the lamp tube type heater of they being enclosed quartz glass tube etc. and enclosing inert gas in inside.As the heater of nickel filament, the nickel filament for the protective wire round is inserted into opaque quartz glass tube etc., also is made into the type that can use in air.Yet because the resistance value of the resistance value of tungsten filament when lighting a lamp during greater than non-lighting a lamp, impulse current bigger when lighting a lamp sometimes can bring infringement to surrounding devices.There is the slow problem of the rate of climb for nickel filament again.Developed the heater of carbon material in order to address these problems.

For example, in international publication number is WO98/59526 number patent documentation, disclosed the heater of the carbon material sintered body that comprises carbon element and metal or semi metallic compound (metal carbides, metal nitride, metal boride, metal silicide, metal oxide, semimetal nitride, semimetal carbide).If according to this embodiment, in the hybrid resin of chlorinated vinyl chloride resin and furane resins, add native graphite micropowder and boron nitride and plasticizer, disperse by the extruding blender.After this, mix with two rollers and make particle by granulator (pelletizer).Particle is squeezed into bar-shaped by the spiral type extrusion equipment, in nitrogen, burns till after dry.Because the emissivity of carbon, makes that the heater of sintered body of carbon material is desirable radiant light heater near black matrix.As carbon heating body in the past, the heater of the use pure carbon cellulosic material that the known Edison of having invents.Yet, because the high-resistance heater of the little and very difficult acquisition of carbon element intrinsic resistance.In above-mentioned conventional art, the material in carbon element behind hybrid metal or semi metallic compound and the employing sintering.Thus, obtaining intrinsic resistance value is that the several times of pure carbon element are to tens of times material.The sintered body of such carbon material is opened shown in the flat 11-54092 communique as the spy as the infrared ray bulb of heater.Phantom with reference to Figure 13 describes for its structure.

In Figure 13, the coiled type part 32 of inner lead 31 its ends of tungsten filament system is installed closely on an end of the resistance heater 1 that forms by carbon material.In an other coiled type part 33 of the central formation of inner lead 31.The other end of described inner lead 31 and the welding of molybdenum foil 6 one ends.On the other end of molybdenum foil 6, engage with outer lead 7 by welding.On the periphery of coiled type part 32, install and fix the metal sleeve 34 of iron, nickel alloy formation.

Open rise record with resistance value of the temperature that is not relevant to the heater that is generated with sintering process by the mixture of carbon material and metal or semi metallic compound in the flat 10-859526 communique above-mentioned spy, its resistance-temperature characteristic is indeterminate.Be used in the heater that above-mentioned spy opens in the infrared ray bulb that flat 11-54092 communique disclosed and have the negative impedance temperature characterisitic that resistance value descends when temperature rises.Therefore, has the characteristic that flows through impulse current at the Shi Buhui that lights a lamp.

Yet, in international publication number is WO98/59526 number patent documentation, do not disclose the concrete example of resistance-temperature characteristic value.The impedance temperature characteristic of heater is an important factors when making heater.That is, under the unsettled situation of the value of impedance temperature characteristic, must confirm its characteristic value and change the area of section of heater or the length of generating heat according to this characteristic value for the manufacturing of each batch.When must above-mentioned operation, can not produce infrared ray bulb in enormous quantities.When promptly allowing to make the heater of impedance temperature characteristic value stabilization, its absolute value is also very important.That is, the resistance when not lighting a lamp, resistance hour does not flow through impulse current when lighting a lamp.Yet because along with the rising resistance of heater temperature reduces, can imagine to become that electric current can constantly increase, temperature further rises such precarious position.That is, when using, heater takes place under the situation of deterioration the danger that resistance value further becomes negative value to take place.Again, on the contrary, when resistance is high when lighting a lamp,, and when its value becomes big, can flow through impulse current, produce and the identical problem of bulb in the past of use tungsten filament though hour do not have problems in its value.

Figure 14 is the cutaway view of the infrared ray bulb of other conventional arts.

In Figure 14, will be welded on from the inner lead 104 that extract out at heater 120 two ends that tungsten filament is rolled into as being made into heating unit assembly body 120a on the metal forming 105 of separately middle end plate.This heating unit assembly body 120a is inserted quartz glass tube 101 and fused silica glass pipe 101 two end portions and utilize metal forming 105 parts to seal and make infrared ray bulb with the state of enclosing inert gas in inside.

In order to address the above problem, to open to have disclosed in flat No. 1154092 communiques as the spy and a kind ofly substitute the heater 120 of spiral in the past and adopt other infrared ray bulbs of example in the past that will comprise that the sintered body that forms bar-shaped carbon material uses as heater.

Open the infrared ray bulb that is disclosed in the flat 11-54092 communique for the spy, owing to adopt the heater of carbon material, the infrared emission rate is higher to be 78～84%.That is, make the infrared emission rate raise by the sintered body that employing comprises carbon material as heater.Because heater is bar-shaped, can as spiral heater in the past, not discharge unnecessary energy to the space again.Moreover, when making that heater is tabular, can make in the distribution of caloradiance, to have directivity.

Open the infrared ray bulb that flat 11-54092 communique is disclosed for the spy, have following problems.

That is,, sagging sometimes because of deadweight when heating when making heater when longer.Again, when the length of heater surpassed certain size, that the pressurization when being shaped sometimes can become was inhomogeneous, can produce bending during sintering.Therefore, finished product can rate descends during fabrication, cost raises.So there is the problem that is difficult to form the long hair hot body.

Again, the problem that has the heat distribution that is difficult to the change heater.

The described lead and energising part of infrared ray bulb of the present invention in order to electrically connect described carbon heating body, electrically connect described lead and described energising part by intrinsic resistance less than described carbon heating body and greater than the parts of described lead, the end of described lead is inserted in the described quartz glass tube and derivation and enclose inert gas in described quartz glass tube to described quartz glass tube outside.The rate of change of the resistivity during infrared ray bulb normal temperature of the present invention when lighting a lamp be-20%～+ 20%, and preferably to comprise the rate of change of resistivity be that the heater of-10%～+ 10% carbon material is made in employing.Like this, though can produce impulse current hardly and when heater generation deterioration temperature can not rise yet.Be about to also can to guarantee safe infrared ray bulb before the fracture of wire even can obtain.

Moreover, between resistance heater and connected lead, accompany the less parts of resistance and be connected, so these parts play a role as heating part.Therefore, can suppress lead is raised to high temperature and can suppresses the deterioration of this part and react with carbon materials.Thus, can realize the infrared ray bulb that reliability is high.The lead that is used for reeling connects, and it is circular that the shape of these parts is preferably.

Even infrared ray bulb of the present invention does not almost have impulse current and can guarantee safety at end of lifetime yet.Again, between heater and lead,, can suppress to make that the temperature of described lead bonding part rises lowlyer, can provide a kind of this part reliability high infrared ray bulb by the parts that intrinsic resistance is little and heat conductivity is high.

If make that described parts are cylindrical, no matter heater is that tabular or round bar shape can both be assembled into it in infrared ray bulb.That is, formation groove and insertion flat board engage on described parts, perhaps form circular hole insertion round bar shape heater and engage.Inner lead with tight chimeric coiling of described columnar component.According to such structure, can realize that the link reliability is high and adopt the infrared ray bulb of the heater that requires shape.

For the present invention's infrared ray bulb on the other hand, described parts are formed by the intrinsic resistance carbon material little and bigger than lead than carbon heating body.Described parts are by carbon material, preferably formed by graphite material.Therefore, heat conductivity is also big, the reliability height of the link of lead because electrical conductivity approaches metal.Because heat conductivity is good, therefore carry out the temperature rising that work can suppress conductor part as thermal component, can obtain long infrared ray bulb of life-span.

In the present invention's infrared ray bulb on the other hand, described lead can be formed by tungsten filament, molybdenum filament or stainless steel wire.The lead that is connected with described carbon heating body or carbon element parts is owing to the fusing point height and the big material of rigidity of tungsten filament, molybdenum filament or stainless steel wire etc. are made, with keeping for a long time with tight chimeric state of reeling.Again, stainless steel wire is compared with tungsten filament or molybdenum filament, and the spring deterioration is little during high temperature.Therefore, be suitable for the Infrared High-Power line bulb of the temperature rising of Wire-wound part.

The present invention's infrared ray bulb on the other hand is provided with roughly on the mid portion at end of the lead that is connected with described carbon heating body or two ends and applies tension force near the spring section of described quartz glass bore to described carbon heating body.Because therefore the diameter of described spring section, can remain in heater the core of quartz glass tube near the internal diameter of quartz glass tube.Because spring section applies tension force to heater, have that heater extends crooked function because of thermal expansion in the time of can preventing to light a lamp again.Usually because tension force acts on heater, so can realize the infrared ray bulb of vibration resistance and impact.

For the present invention's infrared ray bulb on the other hand, enclose the mist of argon gas or nitrogen or argon gas and nitrogen in the inside of described quartz glass tube.

Owing in the quartz glass tube of sealing, enclose argon gas or nitrogen or their mist, be difficult to take place arc discharge, oxidation can not take place in the heater that carbon material forms, and can realize long-life infrared ray bulb.Best, the interior pressure of the gas of feasible sealing is less than atmospheric pressure.That is, even the best back inclosure gas atmosphere of Tiao Zhenging and make that quartz glass tube is inner under the situation of high temperature when lighting a lamp, interior pressure also is slightly smaller than atmospheric pressure.

If according to the infrared ray bulb with the present invention's structure, the very little bulb of heater resistance change rate in the time of can selecting to start.Again, for the profile construction that is used in the sintered body in the heater, because superficial layer comprises than the more carbon content in inside, as the composition of described synthetic radiating light, the radiating light that is discharged by carbon element increases.

As a result, compare, can more approach the emissivity of black matrix, almost equate with the emissivity of carbon element with the heater that exposes inorganic filler at superficial layer in the past.

Again, infrared ray bulb of the present invention is owing to the infrared emission intensity increase of crest wavelength 2～3 μ m part has improved the heat efficiency.Again, because the absorbing wavelength of water and organic substance is 2～3 μ m, the absorption that contains material with respect to organic substance and moisture further increases, and can contain material for organic substance and moisture with less energy and heat.Especially, infrared ray bulb of the present invention can show good result for the organic substance of the skin of various food, human body, coating etc., drying of water etc.

Heating installation of the present invention is the many places that the infrared ray bulb of more than one above-mentioned structure are installed in upside, downside, side or the above-mentioned position of framework.

This heating installation is owing to be equipped with the infrared ray bulb of wavelength near the high IR line emissivity of the absorbing wavelength of organic substance and water, when be used in the radiator of warming oneself, Saunas, heating installation, sufficient heater device, bathroom and the place of changing one's clothes with radiations heat energy with heating drying device etc. to body heating's device in the time, the temperature of the skin that can raise soon.

Certainly, compare with in the past inclosure nickel filament heater tungsten heater and quartz heater, effect significantly improves.

Drying device of the present invention is the many places that the infrared ray bulb of more than one above-mentioned structure are installed in upside, downside, side or the above-mentioned position of framework.

This drying device is owing to the infrared ray bulb of wavelength near the high IR line emissivity of the absorbing wavelength of organic substance and water is installed, and is very suitable for heating of water.As a result, for the drying of the drying of the drying of the drying after the rinsing of photo egative film, clothing, food vessel, bed clothes, contain the coating of organic solvent drying, printed the drying of printed article, the device of drying etc. of printed base plate after cleaning has very good effect.

The carbon heating body that obtains is the round bar shape of diameter 1.50mm, length 500mm.1 * 10 ^-2Heat-treat once more for the carbon heating body of this round bar shape in the vacuum below the Pa.This heat treated once more heat treatment temperature is 1500～1900 ℃ shown in the left hurdle of (table 1).The carbon heating body that makes is like this made the infrared ray bulb of Fig. 1 structure and measures its impedance temperature characteristic.When this infrared ray bulb was applied the 100V alternating voltage, the color temperature of carbon heating body was expressed as 1200 ℃.

Each electricalresistivity under 20 ℃ and 1200 ℃ can try to achieve by following formula (1).

ρ＝RS/L (1)

ρ: resistivity (Ω cm)

R: resistance (Ω)

S: the area of section (cm of heater ²)

L: the length of heater (cm)

According to formula (1), for under temperature shown in the table 1, to carry out once more the infrared ray bulb that heat treated carbon heating body makes, try to achieve the resistivity of 20 ℃ and 1200 ℃ (the surface colour temperature of carbon heating body), try to achieve the rate of change (below, simple note is made rate of change) of 1200 ℃ the resistivity value of resistivity value by experiment with respect to 20 ℃.

(table 1) expression sample plot is tried to achieve by the temperature of each the impedance heater that forms at the sintered body that carries out once more heat treated carbon material under a plurality of different heat treatment temperature resistivity and the rate of change thereof when 20 ℃ and 1200 ℃.

Table 1

Heat treatment temperature (℃)	Electricalresistivity (Ω cm)		Rate of change (%) with respect to the resistivity value under 20 ℃
				20℃	1200℃
	1500	0.0198				0.0147	-25.7％
1600			0.0181	0.0143	-20.8％
	1700	0.0126				0.0111	-11.9％

1800	0.0079	0.00844	6.8％
				1900	0.00609	0.00689	13.7％

Shown in (table 1), when the heat treatment temperature when heat treatment once more was low, rate of change was a negative value.Resistivity value is less when promptly representing to compare 1200 ℃ with 20 ℃ resistivity.Along with heat treatment temperature uprises, rate of change changes to positive direction, rate of change is 0% when heat treatment temperature is near 1800 ℃, under the heat treatment temperature more than this rate of change be on the occasion of, can confirm that promptly the resistivity of comparing under 1200 ℃ with 20 ℃ resistivity is bigger.

According to this experimental result, can judge with respect to the adjustment of the rate of change of the resistivity value under 20 ℃ and can the heat treatment temperature when regulating in a vacuum realize for the handling once more of carbon heating body.Judged already by carrying out heat treatment once more, 20 ℃ with 1200 ℃ under (when normal temperature and high temperature) can make the carbon heating body that the rate of change that has with respect to the resistivity of normal temperature is near the impedance temperature characteristic 0%.Adopt the infrared ray bulb impedance temperature characteristic of this carbon heating body to become mild.Be not 0% carbon heating body by selecting heat treated once more temperature, can making rate of change simply yet as required, so can make the infrared ray bulb of the not mild special requirement of resistance-temperature characteristic simply again, yet.

Secondly, carry out the experiment identical, change heat treated once more temperature and carry out result of experiment shown in (table 2) with (table 1) for tabular carbon heating body.

(table 2)

Heat treatment temperature (℃)	Electricalresistivity (Ω cm)		Rate of change (%) with respect to the resistivity value under 20 ℃
				20℃	1200℃
	1300	0.025				0.0184	-26.4％

(table 2) is illustrated under each heat treatment temperature the experimental result to the heat treated once more rate of change with respect to 20 ℃ of following resistivity values of tabular carbon heating body.

The tabular carbon heating body that is for experiment is to make under the composition identical with round bar shape, identical manufacturing conditions.The width that is shaped as after the burning till of carbon heating body is that 6.1mm, thickness are the tabular of 0.5mm.The mold shape of crimping section that can be by changing extrusion apparatus is made round bar shape, tabular etc. carbon heating body.

With the tabular heater of the carbon element behind the sintering 1 * 10 ^-2Under 1300 ℃～1800 ℃ temperature range, heat-treat once more in the vacuum below the Pa.This heater is assembled in the infrared ray bulb shown in Figure 2, and the resistivity when measuring temperature and being 20 ℃, 1200 ℃ is tried to achieve the rate of change (%) with respect to the resistivity value under 20 ℃.The result is shown in (table 2).By (table 2) as can be known, when heat treatment temperature during less than 1600 ℃, rate of change is a negative value, and become when under greater than 1600 ℃ temperature, heat-treating once more on the occasion of.Along with the rising of heat treatment temperature, rate of change be on the occasion of and become big.

As seen, as the border, rate of change is for more negative value, rate of change is the value of corrigendum when treatment temperature uprises when treatment temperature diminishes with 1600 ℃ of heat treatment temperatures from (table 2).This tendency with (table 1) is identical.Yet, decidable according to the shape of carbon heating body, form and rate of change such as create conditions is zero heat treatment temperature difference.

Key is, has then determined that for the carbon heating body rate of change is zero heat treated once more temperature when having determined composition and shape.If carry out heat treatment once more under this temperature, then can obtain rate of change is zero desirable carbon heating body.If rate of change does not flow through impulse current near zero when then lighting a lamp.Because resistance value does not change in the process that carbon heating body temperature degree rises, so can provide a kind of temperature maintenance that makes the carbon heating body constant and have a safer infrared ray bulb of keeping the self-temperature function.

In the present embodiment, test so that the temperature when lighting a lamp is 1200 ℃, even verified being below or above under the situation of this temperature, the result of present embodiment also can be suitable for.Wish preferably that as the heater of general infrared ray bulb rate of change is zero, and according to present embodiment, can be only realize that by changing heat treated once more temperature the negative value of resistance-temperature characteristic is littler and on the occasion of bigger heater as special requirement.

The rate of change scope that can be applicable to infrared ray electric bulb of the present invention is-20%～+ 20%, and the optimum scope is-10%～+ 10%.That is,, can not consider that then the resistance-temperature characteristic of carbon heating body designs infrared ray bulb if having-10%～+ 10% scope.If in this scope,,, flow through super-high-current at the infrared ray bulb Shi Buhui that lights a lamp because the resistance value during room temperature and the resistance value of adstante febre be close even then be negative rate of change again.For the performance in the lamp practicality, can easily be manufactured on the bulb in the permissible error again.

" the 2nd embodiment "

The 2nd embodiment of the present invention relates to the carbon heating body littler than the carbon heating body rate of change of described the 1st embodiment.Adopt Fig. 1 for the employing of the 2nd embodiment the infrared ray bulb of the carbon heating body less with respect to the rate of change of 20 ℃ of following resistivity values describe.

Fig. 1 is the cutaway view of the infrared ray bulb of the 2nd embodiment.In the figure, as described shown in the table 1 of the 1st embodiment like that, under 1800 ℃, carry out heat treatment once more, making by its rate of change is that the diameter that the sintered body of 6.8% carbon material constitutes is the carbon heating body 1 of the round bar shape of 1.55mm.In the two end portions of this carbon heating body 1 inner lead 4a, the 4b that molybdenum filament forms is installed respectively.Coiled type part 3a, the 3b that molybdenum filament will form on the one end is connected with the tight chimeric screw-type of the two end portions of described carbon heating body 1 respectively.

Described inner lead 4a, 4b have spring section 5a, the 5b that possesses the above coiled type part of at least one circle.The other end of described inner lead 4a, 4b is that the end of molybdenum foil 6a, the 6b of 20 μ m is connected with thickness respectively.The other end of molybdenum foil engages with the outer lead 7a, the 7b that are formed by molybdenum filament by welding respectively.The group body that constitutes is like this inserted in the transparent quartz glass tube 2, on the part of described molybdenum foil 6a, the 6b of its two end portions with described quartz glass tube 2 fusions and seal.

In quartz glass tube 2, to enclose inert gas argon gas 8 less than atmospheric pressure.This infrared ray bulb adopt rate of change with respect to 20 ℃ of resistivity values down be 6.8% with almost near 0% material, so produce impulse current, fully can produce the obstruction that brings owing to noise for surrounding devices at the Shi Buhui that lights a lamp.

Carry out the life experiment of under overvoltage condition (lighting a lamp under the voltage greater than 120V, 130V, 150V or the 200V of rated voltage 100V), lighting a lamp continuously or intermittently lighting a lamp again.The result is its resistance value and rise not significantly or reduce before carbon heating body 1 promptly will fracture of wire, but (heating temp the rises slightly) fracture of wire afterwards that rises slightly at current value.

In order to compare, adopt with respect to the rate of change of 20 ℃ of resistivity values down and carry out life experiment under the described conditions for-23.9% carbon heating body, shortly will fracture of wire before resistance value decline to a great extent, heating temp rises to more than 200 ℃ afterwards and fracture of wire.So, finishing useful life before the fracture of wire if temperature rises, then heater can soften and sagging, then can contact with the inwall of quartz glass tube.The fusion of quartz glass tube meeting as a result, even can produce the danger of breaking.This is to be the reason of negative value owing to described rate of change.Again, when rate of change be on the occasion of and when surpassing 20% because the impulse current value for ignoring, this does not wish to produce.

" the 3rd embodiment "

Adopt Fig. 1 and Fig. 2 that the infrared ray bulb of the present invention the 3rd embodiment is described, in the present embodiment, adopt in the table 2 of described the 1st embodiment and to carry out once more the sintered body that rate of change heat treated, resistivity value under with respect to 20 ℃ is 0.9% carbon material under 1600 ℃.This sintered body is processed into width w is that 6.1mm, thickness t are that 0.5mm, length L are that the infrared ray bulb of the tabular tabular heater 11 of 300mm describes for having adopted.

In Fig. 2, the two end portions of tabular heater 11 engage have resistivity than the resistivity of carbon heating body little and columned parts 12a, 12b that form greater than the carbon material of the resistivity of lead.Its detailed construction example as shown in Figure 3.For example, on the end of parts 12a, form the groove 21 wideer slightly than the thickness of slab of tabular carbon heating body 11.In this groove 21, insert heater 11 and pass through the carbon element solid and engage.

The carbon element solid adopts the micro powder with graphite to be mixed into colloid substance in the organic resin.This carbon element solid is coated on the heater 11 and in the insertion groove 21, in inert gas, burns till after to be dried, the carbonization of organic resin composition is engaged with the temperature more than 1000 ℃.As shown in Figure 2, coiled type part 13a, the 13b on the tight inner lead 14a14b one end that forms by molybdenum filament of reeling on described parts 12a, the 12b chimericly.On inner lead 14a, 14b, form spring section 15a, the 15b of coiled type.

Because the external diameter of spring section 15a, 15b is littler than the internal diameter of quartz glass tube 2, therefore, utilize spring section 15a, the 15b can be on the center of quartz glass tube 2 inside with carbon heating body 11 almost fixed.The other end of inner lead 14a, 14b is connected with the rectangular molybdenum foil 6a of 20 μ m thickness, the end of 6b respectively.On the other end of molybdenum foil 6a, 6b, connect outer lead 7a, the 7b that connects molybdenum filament formation respectively by spot welding.

The group body that is configured to is like this inserted transparent quartz glass tube 2, the air displacement of inside is become after the argon gas, carry out melting sealed and form tabular in the part of molybdenum foil 6a, the 6b at the two ends of quartz glass tube 2.When the part of molybdenum foil 6a, 6b is carried out the two ends of quartz glass tube 2 fusion and is sealed, to seal under the state that described spring section 15a, 15b is applied slightly tension force.As a result, carbon heating body 11 is for being subjected to the state of tension force, the sagging phenomenon so can prevent the 11 adstante febre thermal expansions of carbon heating body usually.Again, even the vibration that applies to infrared ray bulb from the outside, percussion are to heater constantly, because spring section 15a, 15b can absorb above-mentioned vibration, impact, so can realize the infrared ray bulb of vibration resistance, impact.

When the infrared ray bulb to such formation applied 100V voltage, the temperature of carbon heating body 11 rose to about 1100 ℃ after 8 seconds.Because the employing rate of change is 0.9% tabular carbon heating body 11, impulse current is zero.Under the experiment condition of lighting a lamp continuously and intermittently lighting a lamp, carrying out the test in useful life under voltage 130V, 150V or the 200V respectively again.Under all experimental conditions, before carbon heating body 11 closed to an end the life-span, resistance rose slightly and the color temperature of radiating light descends slightly.

As seen, adopted the infrared ray bulb of the present embodiment of the carbon heating body 11 that carries out heat treatment once more and be made into almost not have impulse current, so can use relievedly.Adopt the infrared ray bulb of tabular carbon heating body 11 because it has the structure that inserts tabular heater and engage in the groove 21 of columnar component 12a, 12b, so can obtain the high infrared ray bulb of reliability again.

Since by carbon material preferably graphite form parts 12a, 12b, so heat conductivity is good, also have the function as radiating block.Thus, owing to discharge the heat of the telescoping part of inner lead 14a, 14b, can suppress the rising of its temperature, so improved the reliability of telescoping part greatly.This joint method also can be applicable to the carbon heating body 1 of the round bar shape of the 1st embodiment without a doubt.Moreover, for the carbon heating body of the round bar shape of low power consumption, also inner lead 14a, 14b can be installed directly on the carbon heating body.

" the 4th embodiment "

Describe with reference to the cutaway view of Fig. 4 infrared ray bulb for the present invention the 4th embodiment.In the 4th embodiment, also adopt in the same manner and implemented once more heat treated carbon heating body with the various embodiments described above.

In Fig. 4, be that 6.1mm, thickness t are to engage and identical parts 12a, 12b with graphite cylinder formation shown in Figure 2 on the two ends of tabular carbon heating body 11 of 0.5mm at width w.Coiled type part 13a on the end of the tight inner lead 14a that constitutes by molybdenum filament of reeling on the parts 12a chimericly.

On the mid portion of inner lead 14a, form the spring section 15a that is rolled into coiled type.The coiled type part 26 of the end of the tight inner lead 25 that constitutes by molybdenum filament of reeling on another parts 12b chimericly.

Do not having on the inner lead 25 to form as the spring section 15a on the inner lead 14a as described in being formed on.The structure of so forming is inserted transparent quartz glass tube 2, fused silica glass pipe 2 on the part of molybdenum foil part 6a, the 6b at its two ends and sealing.In the inside of this quartz glass tube 2 to enclose argon gas less than atmospheric pressure.

In the structure of present embodiment, owing on inner lead 25, do not form spring section, can reduce the use amount of high price molybdenum filament, can reduce cost.Make the external diameter of spring section 15a near the internal diameter of described quartz glass tube 2 and make carbon heating body 11 be positioned at the core of quartz glass tube 2 inside, these functions are identical with the structure of described Fig. 2.Because under spring section 15a applies the state of tension force, sealing slightly, so on heater 11, be subjected to pulling force usually.Thus, can prevent the sagging of heater 11 and can absorb vibration and the impact that the outside applies.

In the various embodiments described above, adopted molybdenum filament for inner lead 4a, 4b, 14a, 14b, and also can adopt tungsten filament without a doubt.Moreover the parts during greater than 550 ℃ are effective to elasticity for the temperature of the parts 12a, the 12b that are formed by graphite than molybdenum filament and the better stainless steel wire of tungsten filament under the high temperature.

As inner lead, enumerated the example that adopts wire material, be not limited only to wire material, also can be laminal tungsten, molybdenum, stainless steel.

Also can change transparent quartz glass tube 2 into opaque quartz glass tube without a doubt and use again.Moreover, also can use the quartz glass tube that the surface of glass tube 2 is polished by sandblast.

By selecting heat treated once more temperature, be zero carbon heating body in addition owing to also can make rate of change simply, so can easily make the infrared ray bulb of the uneven special requirement of impedance temperature characteristic again.
